How Installing Energy-Efficient Windows in Antrim Saves You Money
There are quite a few perks of upgrading to energy-efficient windows. A few reasons you may want to consider making the switch are the following:
- More efficient energy use in your home: In Antrim where the winters can be very cold, energy-efficient windows reduce the amount of heat that is lost through your windows, making it easier to keep your home warm.
- Protect your investment: If you have a relatively old home, your windows are most likely in need of replacement. Updating your windows can make your home more comfortable and also help increase the value of your property if you decide to sell.
- Reduce your carbon footprint: In Antrim, you can lower your indirect greenhouse gas emissions by about 286 pounds per year when you install energy-efficient windows.
- Better temperature control in your home: Energy-efficient windows can cut back on how hard your AC needs to work to cool your home.
Estimated Cost of Window Replacement in Antrim
Let's take a look at the cost of installing new windows and the types of services offered by installers.
How Much Do New Windows Cost?
Typically, homeowners in Antrim can expect that most replacement window installations will range from $250 to $1,200, with the average cost at around $600. This is because window installations depend on several factors specific to your home, like the size, material and number of windows you need to replace, as well as the location of your property.
Keep in mind that energy-efficient windows may have a higher price, but Energy Star predicts the upgrade will save you between $101 and $583 per year when replacing single-pane windows and between $27 and $197 per year when replacing double-pane, clear glass windows. Your exact savings will vary depending on your local climate, energy rates and individual home characteristics.
Costs will also vary based on the material you want for your window frames. Aluminum frames are the least expensive. They're sturdy, light and maintenance-free, but provide poor insulation. Vinyl frames are somewhat expensive and provide good insulation. Composite frames made with wood fibers encased in plastic also provide good insulation and are moderately expensive. Wood frames cost the most and are the most in-demand. They're also aesthetically pleasing and provide decent insulation for your home.
What Services do Window Installers Offer?
The first step of a replacement is to figure out whether you need a full-frame or pocket installation.
A full-frame installation replaces the full window, including the windowsill, frame, trim and the window panes. Because this type of installation requires more time and labor, it will cost more than a pocket installation. Pocket installations (or retrofits) involve installing a new window within its existing frame, which makes pocket installations more simple and affordable. But, if the frame has any rot or deterioration, you will likely need a full-frame installation instead.
Your window installer should be able to help you decide which type of installation you need.

How We Choose the Best Window Installers in Antrim
EcoWatch is different from other reviewers since we examine these companies through a sustainability lens. Along with energy efficiency, we evaluated each installer and assigned rankings based on the following methodology:
Service Area
Because this is a guide for Antrim, we gave more points to companies that serve the city. There are other reputable providers that didn't make the cut because of the low odds that they would serve the average homeowner in Antrim.
Work Quality
When installing new windows, the quality and variety of services often plays just as important of a role in insulation and performance as the brand you opt for. We do give window installers higher marks if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.
Customer Reviews
Another self-explanatory yet very important review factor is customer feedback. If the majority of customers don't have good things to say about their service from a certain installer, it won't be featured on EcoWatch.
Cost
Cheaper windows don't necessarily mean better windows, but we know many of our readers try to keep costs low when possible. When analyzing providers' prices, we awarded higher points to companies with reasonable prices and accessible financing rather than "cheaper" services.
Warranty
Protecting your investment in new windows is important to many homeowners. That's why window installation companies that offer lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Last but not least, we like to see companies that have been in the industry for quite some time. Window installation companies that have more experience earn higher rankings by our standards. We like to see at least ten years of experience.
Antrim, PA Window Replacement FAQs
How much does window installation cost?
The national average cost to replace a single window is around $600 but can range between $200 and $1,200, based on several factors. The price is usually dependent on the type and material of the window, the location of your property and the size of the window. Also, bear in mind that energy-efficient windows may cost more initially but can save you hundreds of dollars a year in energy bills.
What type of window is the best for energy efficiency?
Generally, double-pane windows will be more efficient than single-pane windows and windows that don't open are more efficient than windows that do. To be sure you're getting the most energy-efficient windows, look for models with the blue Energy Star certification — they're certified energy-efficient by the U.S. Department of Energy.
Do I really need to use a window installation company?
Unless you have home repair skills and have the time needed to replace your own windows, we recommend hiring a professional installer. The window installation process is quite involved and can take anywhere from four to six hours for a single window. Although it's tempting to try to save money by doing it yourself, hiring a company is a faster, more efficient and much safer alternative.
What time of year is a good time to replace my windows?
While you can install windows any time of year, warmer weather is usually better for installing replacement windows. In addition, it shouldn't be raining, as rain can make the installation more difficult.
